治疗瘴病。四肢厥冷。头汗出不止。两脚感觉像没有一样或偶尔发生呃逆。
川乌、大附子、天雄，以上三味药各等分，水煎服。
瘴病出现四肢厥冷、两脚感觉像没有一样的症状，是脾胃虚寒到了极点，中焦和下焦完全没有阳气的表现。头部大汗淋漓不止，是因为阳气全部浮越于上，即将脱绝。呃逆俗称打嗝，医书里说“绝”是指声音嘶哑、身体不冻僵、像树叶落下时阳气将脱散一样。这些证候，都是因为医生误用了清热攻下的药物，导致病情危急。这个方子用川乌来祛除寒湿、攻逐寒痰；附子补益下焦的虚阳；天雄补益上焦的虚阳。合用这三味药可以收敛心液、壮旺真阳。等到汗止、呃逆停止、四肢温暖，患者就可以恢复生机了。按此法温中固下两种治法，是治疗严重瘴病的必用之法。第（注：此处疑为衍文或特定语境词，依原文保留），瘴病明显可见的，都是极热的证候，而阴寒的证候隐蔽难见。所以用热药治热病的方法，如果不是深通玄妙道理的人，难免都会觉得奇怪。然而必须遵循《内经》“寒因热用、热因寒用”的道理。（注：原文“然必冷冻饮料者”疑似传抄错误，结合后文“乃内经...之义”，此处意译为需遵循内经反治法之理）。
治疗瘴病，症见上盛下虚，旨在调节阴阳升降、补接真气。以及治疗虚风引起的头晕目眩、吐涎沫不止。
黑锡、水银、硫黄、朱砂（各一两，炒制后单独研磨）。
先将干净的铁锅放入铅，先熔化去除杂质一两，洗净后再放入锅中，用铁匙搅拌。将一钱硫黄末逐渐投入，如果有火焰升起不要紧，只要快速搅拌翻炒，使铅熟透失去本性，硫黄都被烧掉，只得到熟铅。于是倒在地下或纸上，使其变硬，然后研磨成细粉，用纱筛出铅粉。剩下的变成朱红色的，再炒、再研、再筛。然后将锅放在慢火上，再次熔化铅粉加入一两硫黄，频频搅拌翻炒，直到出现黄烟，立即拿起放到凉处。过了一会儿再放在火上炒，铅和硫黄都变成黑色，非常调和。然后放到凉处，等它微冷，再放在微火上。一会儿加入水银，用匙搅拌翻炒，千万不要让青烟升起。接着加入朱砂末，频繁翻炒至十分调和，立即倒在地下或纸上使其变硬，另外研磨成粉末，用米糊做成丸药，如绿豆大小。每次服用二十丸，用盐汤送下。
瘴病的证候多表现为上热下寒。这个方子用大热的硫黄，能补益真阳、壮旺真火；辅以朱砂、黑铅、水银三味药，都是至阴之物，性质寒凉，所以能去除严重的格拒之寒，兼有伏阳不得不这样处理。硫黄也被称为将军，功能是破除邪气归正途，消除停滞恢复清朗，挺出阳精，消阴回阳，化魄生魂。所以治疗瘴病用它，能引导上焦的阳气降入下焦，使阴升阳降，达成水火既济的状态。镇坠其阳气，使其不向上浮越向外泄散，元气常温温暖，已患瘴病的人可以得到痊愈，未患病的人可以避免发病。
Treating miasma disease. Coldness of the four limbs. Unceasing sweating on the head. The two feet feel as if they are absent, or occasional hiccups occur.
Chuanwu (Radix Aconiti Kusnezoffii), Dafuzi (Radix Aconiti Lateralis Preparata), Tianxiong (Radix Aconiti Lateralis) in equal parts. Decoct in water and take orally.
Miasma disease presenting with coldness of the four limbs and a sensation that the two feet are absent indicates extreme deficiency-cold of the Spleen and Stomach, with a complete lack of Yang Qi in the Middle and Lower Jiao. Unceasing profuse sweating on the head indicates that Yang Qi is floating entirely to the upper part and is about to collapse. Hiccups (E'ni, 呃逆) are commonly called hiccuping; medical texts describe "Jue" (collapse) as hoarse voice, absence of freezing sensation, resembling falling leaves when Yang Qi is about to depart. These syndromes are caused by physicians mistakenly using cooling and purging herbs, leading to critical conditions. This formula uses Chuanwu to dispel cold-dampness and attack cold-phlegm; Fuzi tonifies the deficient Yang of the Lower Jiao; Tianxiong tonifies the deficient Yang of the Upper Jiao. Used together, they collect Heart fluids and strengthen True Yang. When sweating stops, hiccups cease, and the four limbs become warm, recovery is possible. According to these two methods of warming the Middle and securing the Lower, it is essential for treating severe miasma disease. [Note: 'Di' here may be a textual error or specific context marker]. Obvious miasma diseases are clearly heat syndromes, while Yin-cold syndromes are hidden and difficult to see. Therefore, the method of using hot herbs to treat heat syndromes seems strange to those not versed in profound principles. However, one must adhere to the meaning of "treating cold with heat and heat with cold" from the *Neijing* (Inner Canon), as seen in the discussion on Fuzi.
Treating miasma disease characterized by excess in the upper and deficiency in the lower, aiming to regulate the ascending and descending of Yin and Yang, and to supplement and connect True Qi. Also treats dizziness due to deficiency-wind and incessant spitting of saliva.
Heixi (Lead Tin Alloy), Shuiyin (Mercurium), Liuhuang (Sulfur), Zhusha (Cinnabaris). (Each 1 liang, stir-fried and ground separately).
First, place clean iron into a crucible with lead. Melt first to remove impurities (1 liang). Clean again and put back into the crucible. Use an iron spoon to stir. Gradually add 1 qian of powdered Sulfur. If flames rise, it does not matter; just stir-fry quickly until the lead is cooked and loses its nature, and the Sulfur is burned away, leaving only cooked lead. Then pour onto the ground or paper to harden. Grind finely, sieve through gauze to obtain lead powder. The remaining red substance is stir-fried, ground, and sieved again. Next, place the crucible on a slow fire, melt the lead powder again, add 1 liang of Sulfur, and stir-fry frequently until yellow smoke rises. Immediately remove and place in a cool area. After a short while, return to the fire and stir-fry. The lead and Sulfur turn black and blend perfectly. Place in a cool area. When slightly cool, return to a mild fire. Add Mercurium after a short while, stirring with a spoon. Do not allow blue smoke to rise. Then add powdered Cinnabaris, stir-frying frequently until thoroughly blended. Pour onto the ground or paper to harden. Grind separately into powder. Make pills with rice paste, size of mung beans. Take 20 pills each time, delivered with salt water.
Miasma disease syndromes often present with heat in the upper and cold in the lower. This formula uses Liuhuang (Sulfur), a very hot herb, to supplement True Yang and strengthen True Fire. It is assisted by Zhusha (Cinnabaris), Heiqian (Black Lead), and Shuiyin (Mercurium), which are all extreme Yin substances with cold properties, thus removing severe rebellious cold and addressing latent Yang. Liuhuang is also called General; its function is to break evil and restore righteousness, eliminate stagnation and restore clarity, bring forth Yang essence, dissipate Yin and return Yang, transform Po and generate Hun. Therefore, it is used for miasma to guide Yang Qi from the Upper Jiao down to the Lower Jiao, causing Yin to ascend and Yang to descend, achieving the state of Water and Fire having both met (Shuihuo Jiji). It anchors Yang Qi, preventing it from floating upward and leaking outward, keeping Yuan Qi warm and constant. Those already suffering from miasma will recover; those not yet ill can avoid it.
